Specication of Iietters Patent.- Patented Mar. 11, 1913.

Application led'J'uly 12, 1909. Serial No. 507,089.

To all whom t may concern.'

Be it known that we, DMITRY BALACHOW- SKY and PHILIPPE CAIRE, the former a subject of the Emperor of Russia, the latter a citizen of the Republic of France, both residing in Neuilly-sur-Seine, France, have invented certain new and useful Improvements in or Relating to Driving-Axles, which improvements are fully set orth in the following specification'.

This invention relates to various mechani cal devices applicable to driving axles generally,lthe wheels of which are driven direct by an electric motor with continuous current or alternating single-phase or polyphase current.

The accompanying drawings ,which are given by way of example show in Figure 1 a diagrammatic plan of a driving axle of this kind, in Fig. 2 a diagrammatic side elevation of the same axle, in Fig. 3 the particular shape thatthe axle may have with this method of erecting, Figs. 4 and 5 are modified constructions of the same system. I

It is well known that in locomotives, motor cars or tramways, in the case when the axle and the wheels are driven direct by an electric motor, the movable part of the electric motor is' either keyed direct to the axle, or a space is left between t-he axle itself and a hollow spindle of the electric mot-or, the whole being suspended by means of helical or leaf springs, so that the two shafts shall be capable of relative movement. To that end, a sufficient interval is left between the axle and the hollow spindle. In both cases, the armature being concentric take ofi a damaged motor without first taking off one of the wheels which are generally put on by means of a hydraulic press.

The object of this invention is, therefore,

to attain the following advantages: l. Possif bility of taking off quickly a gearless elec-` tric motor. 2. Protection against shocks and vibrations of all the insulating parts andl of all parts of the motor. 3. Rational suspension of the complete electric motor, reacting in every direction and capable of absorbing and deadening shocks and vibrations. All these advantages are attained without affecting the mechanical strength of the whole.

In Fig. l, the whole of the electric motor is shown inthe center, the part B represents the fixed part and the part A the movable part. In this description these two expressions fixed part and' movable or fingers C engaging with rubber blocks I-I mounted in cylindrical portions R ofthel axle itself. This axle has a special shape as shown in Fig. 3. While being in a single piece, or at least consisting of a number of pieces forming one single part, the axle is provided in the center with a framework forming a space capable of receiving the electric motor after the driving tappets or fingers have been first taken ofl", the said tingers being put in place through the cylindrical openings R after the introduction of the motor. I

Lateral extensions or end-shafts of the axle in question, forming the spindles for the wheels, are provided with a hole of sufficient size to admit a hollow spindle I secured to the fixed part B, the said spindle I being in one piece, or in several pieces secured together. The object of the said spindle isto render the part B fixed. The latter part is held by means of keyed reaction bars K arranged immediately at the point where the said hollow spindle I comes out, that is to say, beyond the extensions of the axle. If the hollow spindle Iis in one piece, it must be withdrawn completely to enable the motor to be removed. Inl the construction shown-in Figs. 1 and 4.-, it consists of two parts secured to the part B. It is sufHcient then to unbolt them and to unscrew them for releasing the part B.-

In the interior of the said hollow spindle is provided the passage for the cables terminating at the movable part, that is to say, going either to a fixed coil or to the brushes.

The opening L enables the cables to be passed to the outside. They can be placed in conduits along the reaction bar K. The reaction bar K rests at its outer end on springs, as shown in Fig. 2, which provide the wheels in spaced relation to each-other and to which the moving part of the motor vis connected by the fingers C and the blocks H or by any other suitable device.
